整理 | GLP1减重宝典内容团队 ▍ 研究显示，司美格鲁肽 的作用原理与之前认为的不同 一项新研究表明，司美格鲁肽、替尔泊肽等减肥药 似乎直接影响新陈代谢，而不仅仅是食欲。 人们以前认为这些药物（统称为胰高血糖素样肽 1 (GLP-1) 类似物）的作用原理是让人感觉更饱，从而吃得更少。 但最近的一项临床试验结果表明事情 并非如此简单 。每天服用 GLP-1 24 周的人体重减轻，新陈代谢也加快。 他们减掉的体重越多，他们的新陈代谢似乎受到的影响就越大，而在研究开始时新陈代谢较慢的人似乎获得的好处最多。 ▍实验证实 司美格鲁肽也在直接影响新陈代谢 研究负责人唐纳·奥谢教授在一份声明中表示："我认为这些新疗法只是让人们吃得更少，这种想法过于简单了。因此，这项研究让我们 对治疗肥胖症的新药的作用机制有了更深入的了解，这是一个令人兴奋的进步。" "研究结果还提供了科学依据，证明肥胖的治疗不仅仅是少吃多动——这只是预防措施。治疗远比这复杂得多。" 图中的蓝色司美格鲁肽注射笔。司美格鲁肽，更常见的名称是 Ozempic，是一种 GLP-1 类似物，可以帮助人们控制血糖和减肥。 GLP-1 类似物是应用最广泛的减肥药物， ...

Core Viewpoint - The article emphasizes the importance of adequate protein intake while using semaglutide, a GLP-1 receptor agonist, for weight loss and overall health maintenance [2][5]. Group 1: Importance of Protein Intake - Sufficient protein intake is crucial during semaglutide treatment to maintain muscle mass [2][4]. - A balanced diet including protein, vegetables, and whole grains is recommended to enhance fiber intake and reduce side effects like constipation [2][5]. Group 2: Mechanism of GLP-1 Drugs - GLP-1 receptor agonists promote insulin secretion by activating GLP-1 receptors on pancreatic beta cells, which is glucose-dependent [6]. - They inhibit glucagon secretion from pancreatic alpha cells, helping to lower blood sugar levels [6]. - GLP-1 drugs delay gastric emptying, controlling postprandial blood sugar spikes [7]. - They also regulate appetite by acting on the brain's appetite centers, aiding in food intake reduction and weight management [8]. Group 3: Metabolic Effects - Research indicates that GLP-1 drugs not only increase satiety but also directly influence metabolism [10]. - Individuals using GLP-1 analogs exhibit increased metabolic activity, leading to higher energy expenditure and potential weight loss [11][13].

Core Insights - Recent research indicates that the mechanism of action for GLP-1 analogs, such as semaglutide, is more complex than previously thought, directly affecting metabolism rather than solely appetite suppression [4][5][6] - The study shows that individuals who lost more weight experienced a greater increase in metabolic rate, particularly those with initially slower metabolism [7][12] Group 1: Mechanism of Action - GLP-1 analogs were initially developed for type 2 diabetes treatment but are now widely used for weight loss due to their ability to improve insulin response to dietary sugars [10] - These medications interact with satiety hormones, slowing digestion and prolonging feelings of fullness, which helps users consume less [11] - A recent randomized controlled trial involving 30 participants demonstrated that GLP-1 analogs also directly enhance metabolic activity, leading to increased energy expenditure [11][12] Group 2: Implications for Obesity Treatment - The findings suggest that obesity treatment is more complex than simply eating less and exercising more, highlighting the need for a deeper understanding of these medications' mechanisms [8][14] - The increase in metabolic activity among users of GLP-1 analogs indicates that these drugs play a significant role in energy consumption, which could lead to more effective weight loss strategies [12][14]
